From Covert Systems, this wireless interviewing system allows someone outside the interviewing room, observing the interview, to send questions to the interviewer during the interrogation, very covertly. Basically, the interviewer wears a covert R.F. receiver on their belt or in a pocket. The receiver is attached to a covert loop that hangs around the neck under the shirt. The audio from the receiver flows through the loop around the neck and inductively couples the audio into the ear piece. Additionally, the unit has 96 channels so that more than one interview can be carried out at one time.
